DEVICE FOR GUIDING THE SLIVER IN SLlVER-BOXES 0F CARDlNG-ENGINES.

EPECIIEICATION forming part of Letters Patent No. 392,275, dated November 6, 1888. Application led May 1` 188B. Serial No. 272,495. (No model.) Patented in England January 15, ISST. No. 65S.

.To al@ whom, it may concern.-

Be 1t known that I, WILLIAM LAWTON, a subject of the Queen of Great Britain, residing at Huddersield, in the county of York, England, have invented certain new and useful Improvements in Devices for Guiding the Sllver 1n Sliver-Boxes of Carding-Engines, (whlch are the subject of Letters Patent of Great Britain, No. 658, dated January 15, 1887 of which the following is a specification.

Thls invention relates to sliver-boxes which are used in carding-engines for receiving the sliver as it leaves the doftingrollers and conveying it away.

Sliver-boxes as heretofore made consist of a long box placed parallel with and beside the doii'er and just below the dofting comb. Through this box an endless belt runs, onto which the sliver falls as it is removed from the doffer by the dofling-comb. This belt 'has usually conveyed the sliver to one side of the cardlng-engine, from whence it was removed. In falling on this belt, and while being carried along the box, the sliver was apt to catch in the sides of the belt or the corners of the box, thereby breaking or injuring the sliver.

The object of my invention is to prevent the catching or breaking of the sliver in the sliverbox and to deliver it from the endless belt in a more compact and concentrated 'form than heretofore.

To this end in carrying out my invention I employ means for keeping the sliver in the center of the sliver-box and the endless belt, consisting of oscillating or reciprocating guide or push plates which work against the sliver on the endless belt and gradually force it into compact form near the center of the belt.

In the accompanying drawings, Figure 1 is a fragmentary perspective view, partly in section, of a carding-engine having my improvements applied thereto. Fig. 2 is a fragmentary side elevation thereof, partlyin section. Fig. 3 is a fragmentary plan thereof, and Fig. 4 is a fragmentary "vertical section cut on line a 4. in Fig. 3. Fig. 5 is a fragmentary plan of a sliver-box, illustrating a modified form of my invention.

Let A represent the frame of the cardingengine, and B the carding-cylinder.

b is the doffer, and c the dofng-co1nb,which is actuated by a vertical rod, d, from a crank, e, situated below the doffer and driven from any suitable part of the carding-engine.

f isthe sliver-box, and g is the endless belt traveling through the box. This belt g plays over pulleys g, mounted at each end of the sliver-box f. (Only one of these pulleys is shown in the drawings.) Two nipping-rollers, h h, mounted over the belt g and roller g', receive the sliver from a funnel-shaped mouthpiece, It', over the belt g and conduct the sliver away. To drive the belt g and the nippingrollers h h, the shaft carrying the pulley g is extended along the frame of the engine, and is provided with a bevel-gear, a, which meshes with an idler or intermediate pinion, a', driven by a spur-gear, b', mounted on the end of the shaft of the doifer b. A spur-gear is fixed on the shaft of the pulley g, and meshes with a similar gear on the shaft of the lower nipping roller h. This latter gear meshes with another on the shaft of the upper nipping-roller h. Thus upon the rotation of the spurgear b the belt g and nipping-rollers h are caused to rotate.

The parts thus far described ae of the ordinary construction now in use on carding-engines.

In applying my invention l provide vertical plates or wingsj and k, which Work over the belt g in the sliver-box f. The plate j is fastened at one end to the sliver-box at-.Z and projects over the endless belt gangularly. The plate k is preferably fastened at one end to the frame of the carding-engine or to the box f by a pin or stud, m, and projects over the belt g toward the plate j. These plates are mounted so that their free ends can be oscillated toward and from the center of the belt g. These plates j and 7c play over the surface of the belt g, and are so arranged that their converging ends play immediately back of the mouth-piece h'. The plates j and 7c are designed to keep the sliver in the center of the belt g, and to gradually work the sliver into this position on the belt the plates are oscillated toward and from each other. For oscillating the plates j and 7c, I connect them,through the medium of slides p p' and connecting-rods n Aand o, with eccentrics s and t, respectively. The plates j and k are connected to the slides p and p by ICC means of arms orpins (j, projecting down from the slides and engaging the free ends of the plates. Thcseplates travel in a track or slideway, (l, which is mounted on a bracket, p2, bolted to thc frame A of the cardingmachine. '.lhis slideway q extends over and across the slivciboxf, just behind the nipping-rollersh, and it supports the mouthpiece It by ties Q, leading from the slideway down to the mouthpiece. The slideway consists of two parallel horizontal grooved tracks, between which the slides p and p travel. These slides are retained in the tracks by projections on the sides of the slides, which take into the grooves in the tracks. The free ends of the plates j and 7c are controlled and supported by the slides p and p, and I prefer to adjust the connection between the slides and plates so that the bottom edges ofthe plates willjust clear the endless belt g. To accomplish this adjustment, I raise er lower the free ends of the platesj and It' relatively to the endless belt y, preferably by means of nuts upon the arms or pins, which project down from the slides p and p' and support the free ends ofthe plates. rlhe connecting-rod n is fastened to the slidcp at one end and to the strap embracing the eccentric at the other. Slide p is connected in like manner by eonneetingrod o with eccentric i. The eccentrics s and i are mounted on ashal't carried in a bracket fastened to the bracket p on the frame A of thc cardingengine, and this shalt is provided with a pulley, a, carrying a belt, e, which belt is driven from a pulley on the fancy77 shaft e, or from any other suitable rotating` part of the eardingengine. The rotation ot' the ecccntries s and i causes, through the connecting parts, the oscillation of the plates j and la, and as the eccentrics are placed diametricall y opposite each other on the eccentric shaft the free ends of the plates j and k are caused to move alternately toward and from each other over the surface of the belt g.

To prevent any waste from adhering to the nipping-rollers h h, and thereby injuring the sliver, I provide the uppcrcdge of the mouthpiece It with a cover of felt, t, which comes in contact with the lower roller lt and rubs oft' any waste that may adhere to that roller.

For cleaning the upper roller '/t, I provide a bar, Aze, covered with felt, u, on its lower side. lhis bar w is held by its ends in the frame supporting the rollers l1, and its lower and feltcd side rests on the top of the upper nipping-roller `/z and wipes the adhering waste therefrom as the roller revolves.

In operation the sliver, after passing the ordinary card-flats of the carding-cngine, is removed from the carding-cylindcr by the dollcr I. The doller carries the sliver over the sliver-box f, when the sliver is removed from the doffer bythe dofling-eomb c and falls upon the endless traveling beltf/in the sliverbox f. The bcltg carries the sliver out toward the nipping-rollers hy h. As the sliver is carried out by the belt y, the oscillating plutesj and act on the sliver and gradually push or rnb it into a compact mass in thecentral part of the belt, delivering the sliver at their free ends into the mouth-piece h', which feeds it to the nipping-rollers li h through a reduced nozzle. The sliver is carried under and up in front of the lower nipping-roller h and back between the upper and lower nippingrollcrs, and is delivered from behind the upper nipping-roller h, from whence it may be conveyed where desired.

In Fig. 5 I have shown a formof my invention, wherein the plate L is stationary, it being fixed to the frame ofthe cardingcnginc by two stays. In this figure the plate]l is shown as having a lateral reeiprocatory movement over the surface of the belt g toward and from the plate k. This movement is imparted to it by two pitmen, n a', which are connected to the plate j at one end and to cranks on the shaft carrying the driving-pulley n, at the other end; By this construction the sliver on the belt g is pushed up toward the plate 7s by the reeiprocation of the plate j.

I may make the plates j and k of wood or sheet metal, and the other parts of the cardingenginc and sliver-box may be made of any suitable material,such as is commonly used for these machines.

It will be readily understood that various details of my invention may be altered without changing the character of my invention, the construction and operation shown and described being the preferred form in which I use it. For example, the plates j and lc may be oscillated by any suitable mechanism instead of the eccentrics shown; also in some machines the plates j and L may be constructed so that one is stationary and the other movable, as shown in Fig. 5. It will also be understood that, instead of the slideway and slides used in oscillating the plates j and 7:, these plates may be connected directly with the connecting-rods n and 0. Nor is it essential that a mouth-piece, h', be used in connection with my sliver-box. ll'n cases where there is no sliverbox used, and the endless belt alone is relied upon to carry the sliver away from the doffer, my oscillating plates may be used with the same advantage as when used with a sli vcr-box,

Iclaim as my invention, in a carding-engine or analogous machine, the following novel featurcs and combinations, substantially as hereinbcfore set forth, namely:

l. The combination, with an endless traveling belt, ofi a laterally-reciprocating plate arranged to move transversely over the surface.
